Facts & Perceptions
As market participants, our
actions are driven by primitive emotions of greed, fear, hopes and herd
instincts. The internal battles, between
our reptilian brain and our neocortex, are the engines powering the stock
market and giving it its impetus.
While a utilitarian rational brain would command to buy more when
prices are falling, most market participants prefer to buy rising prices or
sell when prices are falling. Without emotions there would be no action.
Without action and emotional inefficiencies, there would be no market. Man’s "failabilty" is the source of progress.
For every stock you want to buy,
you need to find a willing seller. For every stock you want to sell, you need to
find a willing buyer. You need two to make a market, like you need two to
tango.
If one accepts the idea that in a
closed system where the money in circulation does not change and where taxes
and commissions can be ignored, any trade is a zero sum game, that would mean
that for every winning trade you would effectively need a sucker on the other
side. Of course, they are no willing losers in the market. Most market
participants act with their self interest and self preservation in mind, such
that the key reason to go on the other side of the trade, might well be a
simple matter of perspective.
A day trader would be happy to
take a profit and sell to long term investor who would look to accumulate for
the long run. The same long term investor might want to buy a growth growth,
which the short seller would be happy to sell as part of its portfolio hedging
strategy.
These different perspectives are the very reason markets exist,
but don’t stop there. They also reflect our imperfect knowledge of reality. We only see fragments of that
reality while our conscious attention can only focus on a very small corner of
that reality at any single time. This tends to distort one’s focus and
attention. As Charlie Munger likes to remind people, „to the man with a hammer
every problem looks like a nail“. A value investor would focus on certain
criteria, while the trend follower would focus on others. If the stock market
operates like a beauty contest, it is worth recalling that beauty lies in the
eyes of the beholder.
To add to the complexity, reality
in market is not static. A share price is not looking at the past or present
but at a more uncertain and ever changing future, a future that is shaped by
our collective visions and social moods and their capacity to shape our reality.
Back in the nineteenth century a shoe company sent
two salespeople to India to assess the market opportunity or so goes the story.
After a few weeks, the first one wires back: „nobody wears shoes: there is no
market!“. A day later, the second one telegraphs „nobody wears shoes: huge
potential!“ Clearly, both salespeople saw the same things, but their different
interpretation of the same reality was effectively a matter of perspective.
This is obviously the key dimension that separates
social science from physics. In the physical world, an action produces a clear
predicable reaction, a fact is always the same fact that unfolds
independently of any statements that relate to them.
In the social world, the same action can produce
different perceptions and therefore different reactions and is subject to many
more distortions. Social events have thinking participants whose decisions
greatly influence the course of events, not independently of phenomenon, but as
active interactive participants. The same text can be interpreted differently
depending on the context.
In a social world, a perception can become a fact
and a new fact can change perception, the same way a perception can influence
the facts. This constant feedback loops between fact and perception is creating
what George Soros (one of our many heroes) name „reflexive“ loop, the type of
self-reinforcing/fulfilling circular reference at the heart of every major
bubbles (like the tulip bubble below or bitcoin bubble recently) and also explaining one the paradoxes of risk.
One could well imagine that if
the shoe company had followed the second sales person‘ advice and started
converting local customers to the idea of wearing comfortable shoes, the vision
would have probably eventually become reality. In fact, all great inventions
start like this, a vision of the future that has yet to be embraced and adopted
by the masses.
The internet bubble sucked a lot
of money from investors but the perception of what the internet could be,
helped raise the billions that eventually created the infrastructure that made
it a reality. A company burning cash like Netflix can still attract investors
lured by its growth story, while the high price of its shares does give the
company a currency to buy the content and the earnings it cannot produce on its
own. These types of reality distortion as Steve Jobs named them is how
perceptions become reality.
Greece came out of the Great Recession in 2011
like an emperor with no clothes. As long as the market was happy to lend to its
government, its EUR-denominated government debt was strong and the country
could borrow cheaply to finance its deficit. However, when the perception
changed, its credit spreads spiked, its interest burden surged and its debt
ballooned. The perception changed the fact, which in turned changed the
perception, in a death spiral that led the countries to the brink of
default.
The emperor had no cloth and the bond vigilantes
by stating it loud helped the market wake up to the fact. However, had the market
decided that the emperor had clothes, then it would have given the emperor the
time to sell its invisible clothes and get the money to buy real clothes, which
is pretty much what happened when the German emperor accepted to lend some of
its invisible clothes to its Greek cousins.
We cannot see reality as it is,
but only a reflection of it. We fill in a lot of blanks with our minds and rely
on incomplete perception of reality as the basis of our decisions. A man sees
what he or she likes to see based on their particular emotional and
physiological state. Perceptions vary from person to person. The same person
can see things differently over time. Even the same painter can paint the same
subject over and over again, yet never produces the same painting. We also
assign different meanings to what we perceive. Therefore, with time, people
change their perspective of reality or simply give it a different meaning.
Reality is all relative and a matter of perspective. Beauty is in the eye of
the beholder. This famous picture by Toulouse-Lautrec is either a a young or an
old lady depending on how you look at it. The picture hasn't really changed,
what changes is how your emphasis of certain traits assigned to them different
meaning.
For the investor, the challenge
is manyfold as it requires not just be sure of the facts, but also be conscious
of opinions and how these facts are
perceived by the majority and social moods can change the reality of the facts.
As a result, an investor should never assume, never predict and never trust
information at face value.
The job of an investor is to ask
questions. The answers may change, but the questions are always the same. Those
who know all the answers generally do not even understand the questions. In a
survival game, only the paranoiacs survive. So keep on asking questions and
challenging the consensus.
As discussed in our previous
post,
always look at your investment
cases from the opposite side of the trade. If you want to solve a problem, said
Einstein, „invert, always invert“. When we want to buy a stock, we first look
at the reasons to sell it. If you can’t find a good one or selling appears too
risky, then it’s probably a buy. The reverse applies to shorts.
There is no facts, only
interpretations, only perceptions. Even earnings are opinions. Cash might be seen as a fact, but it can also
be manipulated. That is why an investor should cherish diversity of views and look
for people thinking outside the box, looking at things from different angles
and acquire different perspectives. Never forget that every information is a
creation and a reflection of a tiny piece of reality.
As such investing can be approach
like a puzzle or a game of bridge, where the game is to gather clues of a more
complex reality in order to see the full picture. Here, there are different
strategies. Our preferred approach is the one used by eagles,which look at the
big picture from far above, start seeing patterns, get a bit closer, start to
narrow down the patterns, get a bit closer and eventually focus on the prey
before striking. This is a top down approach. However, the opposite approach
works well too. They say the devil is in the details, such that sometime an
individual situation can reveal a bigger theme, like a tree can hide a big
forest.
The key is to use as many mental
models, what Charlie Munger calls a latticework of mental models to filter
through the tons of data and opinions and narrow it down to some of the
essential traits that would fit your criteria. It is not the answers that
count, but the quality of the questions and the quality of the filters. As the
answers may change, never stop questioning.
In the absence of independent objective criterion, all
decisions are based on bias and distorted perceptions of reality and lack of
perfect knowledge. Therefore, market participants must rely on two functions:
the cognitive one (logic based and fundamental based) and the manipulative one
(opinion based and perception based). Therefore, it is key to always check the
facts and the sources we use as the basis of our opinions and always remember
that things are rarely what they seem and the world is at it is and not as it
should be.
One should therefore avoid
looking at the world with prejudice and other self limiting beliefs and avoid
listening to "theorists" or opinions based on biases rather than facts.
The list
of behavioural pitfalls that tend to distort perceptions of reality is a useful guide of what to be on look out, not
just to avoid falling victim of other people’s narrative fallacies but also to
keep one’s own perception of reality in check.
Biases
(preconceived ideas, prejudice)
- weighting recent experiences
more heavily than they should.
- bias for the familiar: don’t
confuse familiarity with knowledge
- optimistic (biological
default state) / pessimistic bias (rational state)
- herd instinct (beliefs of
safety, collective rationalisation)
outcome/hindsight/confirmation
bias
|
Hubris
(refers to overinflated egos, which can lead to lose sense of reality and
overconfidence)
- take things personally (the
market does not know you exist)
- overbearing pride,
confidence, illusion of control
- loss aversion, fear of
uncertainty
- greed and illusion of control
|
Imperfect
accumulation of facts
- Anchoring on irrelevant data:
avoid information overload
- Projecting immediate past
into distant future
- Overestimating the likelihood
of events based on recent memorable events
- Misunderstanding randomness:
seeing patterns that do not exist
- More information does not
mean more accuracy
|
Heuristics
(improper use of short cuts and „rules of thumbs“)
- pavlovian reflexes
- narrow framing
- anchoring
- use of intuition
